LOG LIFTING AND TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 408,760, dated August 13, 1889.

Application filed December 17, 1888. Serial No. 293,929. (No model.)

and State of Arkansas, haveinvented a new and useful Log-Lifting and Log-Turning Machine, of which the following is a specification. The object of my invention is, first, to put a log onto the carriage of a saw-mill; second,

to turn the log over or partly over while being sawed; third, to slide asquare stick or partly square stick onto the carriage after having been turned. I attain these objects by the mechanism'illu'strated in the accompanying drawing, -in which drawing I have shown a perspective view of my invention.

Similar letters referto similarparts throu ghout the drawing.

a is the mill-floor; b, logways; c, log-lifters; a, shaft on which arms d and eccentrics f, that raise log-lifters c, are fastened; q, pins on which log-lifters c c 0 swing; 25, pin on side of logwa'ys b, to which rope s is attached; at, hook to turn log 11 Z, bolt on which hook at swings, and which also receives pitman m,- 1), hole in hook n toattach rope s; m, pitman of engine h; 70, pin in cross-head g; 1-1", guides; j, piston-rod of engine h; o, carriage of saw-mill; w w, head-blocks; w or, knees of head-blocks; y y, log.

Operation: Toturn a log, apply steam to the upper end of the engine 72, which will draw down the arm d, carrying the hook n,

and the hook at will pull the log y forward until it strikes the log-lifters c, and the hook at will roll the log y forward onto thelog-lifters 0. Then apply steam to the lower end of the engine h, and the arms cl will push the log y onto the head-blocks w and against the knees 00. It will be noticed that when the log y/y is turned forward onto the log-lifters 0 they are raised by the eccentrics fabove the head-blocks 10, which admits of the log 'y being shoved back onto the headblocks w. When the log y has been turned and shovedback, pull on the rope s where it is attached to pin t and the hook n will be raised so as to clear the logy y. Then apply steam to the upper end of the engine h, and the arms 01 will be drawn down below the logwaysb and the hook at will drop by the side of its arm cl, and this armol being fastened to the shaft and the other arms being also fastened to the shaft 6 the arms d are all drawn below the top of the logways b, and the eccentrics f being also fast to shaft 6 they are carried back when the shaft 6 turns, causing the log-lifters c to also recede by gravitation below the top of the logways b. When all the arms d and the log-lifters c are drawn below thelogways 1), another round log can be rolled over them to a point between where the end of the arms cl will rise above the top of the logways b and headblocks 10. To put this round log onto the v head-blocks 4.0, apply steam to the lower end of the engine 71, and the arm (1 rising will turn the shaft 6, which will cause the eccentriosf to raise the log-lifters 0 above the top of the logways 19, carrying the log 'y above the head-blocks 20, so that the arms d can either push or roll the log 7 onto the head-blocks w.

the logways b and the hook at hanging down, first pull on the rope s at t, and the hook n will be raised into the air, so as to clear the log y. Then apply steam to the lower end of engine, and the hook n will be thrown over the log y, and the eccentrics f will raise the log-lifters a, so as to catch the log y as it slides forward and make it turn by the pulling of the hook n, as heretofore described.

What I claim, and desire to secure by Letters Patent, is-

1. In a machine for turning and lifting logs, the combination, with an engine, a rockshaft, an arm secured to the shaft, a hook pivoted to the free end of the arm, a pitmanrod pivotally connecting the hook with the piston-rod of the engine, and guides r, for

regulating the direction of movement of the.
